The background: Passion Pit, who have played just a handful of shows to date but are already generating a cyber-din online, may have either been named after an ancient Traci Lords/John Holmes skin-flick or from the code-words for drive-in movie theatres where teenagers go to make out, but what they really do is kids' stuff, only in a good way. They were one of the buzz-bands at the recent CMJ festival in New York, where they won elated responses to their excitable lo-fi electronic pop, and you can see why people were so excited. Passion Pit's music is heavy on the handclaps and children's TV melodies, which are played on synths and sung by young men whose squeakily high-pitched, shouty falsettos are designed less to suggest androgyny and feminisation than boys in an abnormally heightened state of innocent, adolescent arousal. "I wrote this record to capture and convey that feeling where something feels TOO good," says mainman Angelakos of the songs on their Chunk of Change EP, which he wrote as a Valentine's Day gift for his girlfriend and is issued by the people who brought us Les Savy Fav and the Hold Steady. "I like painfully beautiful, euphoric, blissful, sad, hopeful, and completely honest pop music," he adds, hence the joyous juvenilia of their electro-twee ditties, their euphoric gleetronica, with its intimations of ecstasy and the ennui that inevitably follows rapture.

Angelakos, who writes and records everything himself and is something of a perfectionist, is a fan of both the deceptively easy-listening songcraft of Randy Newman and the machine disco of Giorgio Moroder, and in a way Passion Pit do, like last week's best New Band of the Day, Empire of the Sun, make MOR you can dance to – bassist Apruzzese even compares the band to 70s soft rock behemoths Chicago while half of them, especially the beardy ones, look like Rupert Holmes of Escape (The Piña Colada Song) infamy. But there's also something of the chuck-it-all-in-the-mix, delirious DIY sample-pop of Avalanches, Shortwave Set and The Go! Team in what Passion Pit do, as well as traces of Hot Chip's electronic reveries, or the Lips/Rev/MGMT school of rock bliss-out. There are odd time signatures and song structures here – Cuddle Fuddle has been described as "25th century ragtime" – but there are also moments of genuine pathos and undiluted, unalloyed joy. The buzz: "I'm all tripped-out smiley-faced on this shim-sham of wonderment."

The truth: Hey, so are we.

Most likely to: Bring joy.

Least likely to: Bring Joy Division.
